A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.
